To all @cham it ma concern; i bile engine'which are in certain typesoi Be it knownt at I,4 JoHnC. Avans, a cars, surrounded interrhediate of the endsof citizen "of the United States residmgf at the cylinders b e'horizontall projectiniy lSuperior, in the county of bougies and' reinforcing she f, as indicated1 at' 2, a 5 State of Wisconsin, have invented certain abov"e `which rests the exhaust manifold 3, 55 new and useful Improvements' in' Autqmo'- each individual exhaust pipe 4 leidingfrom bile-Heaters, of which the following 1s a its respective cylinder at a point some dissgecication, reference being had theremto tance above the shelf 2. v t e' accompanying drawing.

of the exhaust pipes l and attached the member 7 by the bolts 10. The remaining portion 5 of the conduit is then put in place over the manifold and the exhaust ipes, the flange 6 being securely bolted to t e flange 1l by the boits 12 und the buse flange M of the member 5 secured to the engine shelf 2 by the bolts 15.

The rear end of the conduit is made somewhat funnel shaped as at 16, the upper wall being inclined upwardly from thebody portion and the outer side wall 4being inclined outwardly -from the body portion conforming with the shape of the shelf 2 es found on the engine.

The outer terminal ed es of the funnel shaped portion are turn outwardl forming flanges 17 which abut against t dash boord 18 of thel automobile and are secured theretoby suitable bolts or screws 19.

Within the opening formed through the dash board opposite the mouth of the conduit. is installed any suitable form of regis` ter indicated at 2.0 und which is provided with n foot lever 21 for opening or closing the shutters olf the register as is commonly known. l

The forward end of the conduit is mede flaring as at 22 for the proper reception of the aircurrents :is they enter the front portion of the engine hood und transversely positioned adjacent. the bottom of the forward end and within the Hering mouth is mounted e. shaft 23 which carries a plurality of wire` screens 24 united by suitable rivets 25. This pack of screens is of u size to snugly fit, within the front end of the conduit and form a screened closure for same or it may be turned down forwardly as indicated in dotted lines, Fig. 4, when the heatel'is not being used. It is found in practice that u plur-.ility of screens placed together as illustrated in the drawings gives very much better resuits thun a single screen which appears to be due to the fact that the current of air passin therethrough into the conduit is more t oroughly broken up and itshorizontal movement retarded thus causing the temperature to ri'swend the ability of the nir to carry the heet from the manifold greatly improved. e

It is also determined that when the screen closure 24 is lowered as illustrated in the dotted lines and the register 20 o ned, but very little heat is, carried throng the conduit.

Having thus described my invention what I claimI as new and desire to secure by Letters Patent, is:

1. The combination with en internal combustion engine having a laterally projecting exhaust pipe from each c linder of the engine entering a. horizonte ly disposed maniold, of a febricated air conducting conduit surrounding the mamtold und comprising n base, un opstanding downwardly curved nuljor portion tixed to the bnse,n spurred minor portion fixed to the buse between thv nninifold :und the engine cylinders mid u third portion, ovcrlztppmg und removably lixod to the minor portion and valso removably fixed to the Innjor portion whereby thc device muy be quickly' und conveniently applied` to or removed from the manifold of the engine.

The combination with nu internal combustion engine hnvin n laterally projecting :shelf therenlmut, nn un exhaust manifold :thrive the shelf, of n 4fabricated air conducting cond uit comprising un upstnnding downwnrdly arched major portion fixed to the shelf I.ind overlapping the manifold, :in u standing spaced minor portion between t. c nuuiifold und. the cylinders of the engine nlso fixed to the shelf und nn intermediary poulen iix'ed to sind unitingr both of the other portions, holes, half in the urched muor portion nud hull' iu the intermediate portion through which the exhaust pipes of the cugino extend und moans for controlling the passage of nir through the conduit.

4. The combination with an automobile having nu internal coinbustion engine with a laterally rojectin shelf below the munifold thereoij und e 4fish 'boa-rd adjacent the rein of the engine, of a. substantially inverted U-shnpcd air conduit fixed to the shelf its entire length and having n separable sectional inner wnll intermediate of the manifold und the engine, said conduit having un open forward end and u substantially funnel shaped rear end attached to and discharging through n. domper rontrolledfopening in the dash board substrintinll y es described.
